Key Technologies of Laser Tube Cutting

The traditional tube cutting method is difficult to meet high production requirements, and Tube parts placed by non-traditional methods are generally of high quality the cut surface is less than good.

If this tube machining uses the traditional method, it is undefined low, but also difficult to meet the ideal requirements, and some not even acceptable. However, nowadays there are many technologies that have been developed in depth laser cutting tubes, including:

1. Light Guiding and Focusing System
   In laser cutting devices, the function of the light guiding system is to direct the beam output from the laser generator to the cutting head of the focusing light path. For tube laser cutting, if a high quality cutting gap is to be obtained, a small diameter and high power focus point is required, which allows the laser generator to run low-order mode outputs. In tube laser cutting, in order to obtain a relatively small beam focusing diameter, the laser must have a small transverse mode sequence time which is the preferred base mode.

2. Automatic Control of Laser Cutting Focus Position
   To ensure the quality of tube laser cutting, keeping focus on the vertical direction of the workpiece surface with measuring tools and automatic control is the key to tube laser cutting. At present, it is able to integrate the laser focus position with the direct axis (XYZ) of the laser processing system, which makes the laser cutting head movement lighter and more flexible, and the focus position can be understood well, so as to avoid the impact of the cutting head with the cutting pipe or object. others during processing.

3. Cutting Head Pass Control
   In tube cutting, the tube to be processed is included in the curved surface plane, and the tube shape is relatively complicated. If programmed and carried out by conventional methods, there will be certain difficulties. It requires the operator to select the correct machining path and appropriate reference point according to the machining process requirements, and to use a numerical control system to record the feed conditions of each axis and the coordinates of the reference points, and then record the machining process coordinates and generate machining programs through the linear interpolation function. and coiling of the laser cutting system. Therefore, using the automatic vertical function of laser beam and tube cutting is also one of the important technicalities of tube laser cutting.

Currently, Duta Laserindo Metal has used modern methods with sophisticated technology in the laser tube cutting process, not only high processing efficiency, but also very easy to achieve ideal processing requirements.
